Product Description:

bulb is a creative product comparing with common LED bulb. By adopting artistical design idea, SFT applies Magnolia shape into the LED bulb and creates the patented distributing cavity technology. With this technology, the omnidirectional lighting and better thermal dissipation can be realized. The lamp offers naturally warm light with beautiful sparking effect, while consuming 5W energy only, which meets the Energy Star standard.

Q:What are the requirements of the LED series inspection specification for bulb bulbs?

The temperature rise of the finished lamp is not more than 120K. The temperature rise is equivalent to the maximum value of 60W incandescent lamp.

Q:LED bulb bulbs, do you need 3C certification now?

LED bulb is not required to do 3C certification, and can not do 3C certification, LED bulb is a light source, not lamps, there is no company's LED bulb made 3C, CQC done there.

Q:Secret LED bulb bubble price difference why so big?

Power Supply。 Good quality will be equipped with power supply, usually in the lamp cavity. And low prices are put on the lamp board with several capacitive resistance to deal with

Q:Will the power of the LED bulb grow longer and longer? Why?

Voltage problems, as well as unstable factors.Long time no change, should

Q:What's the cause of the noise during the aging of LED bulb bulbs?

The sound may be come from the power supply module components aging or faulty soldering and desoldering. LED long life, but may also be some problems.

Q:LED what is the glue between the aluminum base of the bulb and the cooling aluminum?

It is best not to direct contact with glue, glue because the thermal conductivity of aluminum than a lot of difference, even a thin layer will reduce the heat out of the speed of the screw can be used to aluminum plate and aluminum fastening together, the contact surface is smooth, when necessary, can use some conductive silicone grease amount

Q:What does "A19" mean in LED A19 bulb?

A19 is the European A60: represents the outer diameter 60mm=19/8*25.4=60.325mm, such as the diameter of the A19 bulb. "D=19*1/8", multiplied by 25.4, is the diameter of the bulb in mm units. The source of this formula is the same as the T8 tube: "X" in Tx means that the diameter of the tube is x times 1/8 inches, so the diameter of T8 is 1/8 inches x 8=1 inches, or 25.4mm

Q:Detailed description of LED bulb lamp

High purity aluminum reflector, radiator, acrylic glass cover, high power LED light source, high efficiency imported constant current source. 2. The bulb has high luminous efficiency and good environmental protection performance. It does not contain harmful substances, has no pollution to the environment, does not have infrared rays and ultraviolet rays, and avoids harm to the human body, and belongs to the green lighting products. 3, PC light shield, optional transparent or matte, to prevent glare and effectively protect the LED lamp, unique optical design, light distribution. 4, good color, to show a true color of things, a variety of color options, to meet the different needs of the environment, eliminating the traditional lamp color temperature depression caused by excessively high or low, the Department of visual comfort, improve the working efficiency of workers. 5, the bulb of the spiral points E27 and E40, easy installation, alternative to the traditional 65W125W energy-saving lamps. 6, the bulb is made of high quality aluminum alloy for shell production, good corrosion resistance, long service life, energy-saving effect is obvious. 7, bulb 30W installation height of 3-4 meters, 50W installation height of 5-6 meters.

Q:LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!

If it is to continue the glimmer of minutes, the main side is the use of resistance and step-down circuit caused by the normal phenomenon. It's very rare for the factory to use this old model to make LED balls. Circuits that run for hours or all day on the side of the LED bubble are out of order. It's not normal to shine for so long. Now most of the LED bulb is using IC constant current supply circuit, no such situation has emerged.

Q:How to identify Ic constant current LED bulb?

The general user how to judge whether the bulb with constant current IC power supply, the general bulb is divided into three kinds, one is the RC driven RC drives are the most simple, because the cost is very low power small bulb and lamp using the scheme of small power LED bulb is often driven by RC, RC driving disadvantage is LED current with voltage fluctuation is changed, the brightness will change, so the resistance capacitance in the price is cheaper and less demanding bulb drive only, one with the IC LED driver, this there is also a constant current power supply, but the precision of constant current IC is not high, this power can only be used in the 220V voltage, the voltage fluctuation of relatively large area will affect the brightness of the LED lamp, and the stability of the power supply is relatively poor, life is better than Relatively short, easy to issue, this power supply is only a three - stage tube and two regulators circuit very...
